DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 4 The utility model provides a technical solution: a copper terminal with a double-end quick lock structure, including a wiring plug barrel 1, a plug barrel bottom buckle 2, a quick lock component 3, an opening groove 4, a limiting protrusion 5, an external ring buckle 6, a positioning block 7, a rubber outer skin 8, a series plate 9 and a fixed block 10. The plug barrel bottom buckle 2 is provided at the rear end of the wiring plug barrel 1, and the front end of the wiring plug barrel 1 is provided with an opening groove 4, so that the front end of the wiring plug barrel 1 is divided into an upper and lower part, the quick lock component 3 is assembled on the external ring buckle 6, and the two external ring buckles 6 are connected by setting a series plate 9, and the surface of the external ring buckle 6 is arranged A plurality of positioning blocks 7 are installed, and a rubber cover 8 is added to each positioning block 7. A fixed stopper 10 is installed on the top surface of the series plate 9. The quick lock assembly 3 includes a buckle 31, a lock cylinder 32, an external buckle plate 33, an external sleeve 34, a control spring 35 and an internal rod 36. The left and right ends of the buckle 31 are respectively connected to the lock cylinder 32, and the left and right lock cylinders 32 are also connected by setting an internal rod 36. The surface of the internal rod 36 is wrapped with a control spring 35, and the outer periphery of the control spring 35 is sleeved with an external sleeve 34, and the external sleeve 34 is also equipped with an external buckle plate 33.

[0020] As the first embodiment of the utility model: the left and right ends of the built-in rod 36 extend into the interior of the lock cylinder 32 and are fixed to the lock core part of the lock cylinder 32. The design can control the left and right lock cylinders 32 at the same time through the built-in rod 36. The structure is simple and convenient, which helps to reduce the workload of operators. A notch matching the size of the opening groove 4 is reserved on the external ring buckle 6. The design structure is rigorous and helps to control the range of the inward pressing of the wiring plug 1 to avoid excessive pressing of the wiring plug 1 to damage the internal wires. The lock cylinders 32 at the left and right ends are welded to the fixed block 10 on the surface of the series plate 9. The design of adding a fixed stopper 10 helps to enhance the firmness of the lock cylinder 32 on the surface of the series plate 9 and improve the use effect. The control spring 35 is wrapped around the outer wall of the built-in rod 36, and the front and rear ends of the control spring 35 just rest against the inner wall of the external sleeve 34. The design affects the restriction of the built-in rod 36 by the control spring 35 through the rotation of the external sleeve 34, thereby driving the lock cylinder 32. A plurality of regularly sized limiting protrusions 5 are welded on the inner wall of the wiring plug 1. The design squeezes the wires on the inner wall of the wiring plug 1 through the plurality of limiting protrusions 5, which helps to strengthen the connection between the wiring plug 1 and the wires.

[0021] As a second embodiment of the present invention: after aligning the wire with the wiring plug 1 and inserting it, the staff first bends the external buckle plate 33 in the quick lock assembly 3 upwards, so that the external sleeve 34 will rotate together, and the ends of the control spring 35 are stuck on the external sleeve 34, so the control spring 35 will be squeezed and loosened, so that the lock core in the lock cylinder 32 connected to the built-in rod 36 will be linked to the built-in rod 36 to open, and the fixed control of the lock core in the lock cylinder 32 will be lost, and the buckle 31 will be loose, and can be taken down from the locking block 7 on the external buckle 6, and then the external After the connecting ring buckle 6 is inserted into the terminal plug barrel 1, the staff will tighten the external ring buckle 6 in the same way, put the buckle 31 on the blocking block 7, and then press the external buckle plate 33 downwards. The control spring 35 compresses the built-in rod 36 to allow the lock core tube 32 at both ends to lock the buckle 31. In this way, the buckle 31 will be tightly stuck in the rubber outer skin 8 in the blocking block 7, and the upper and lower parts of the front end of the terminal plug barrel 1 separated by the opening groove 4 will be squeezed close to each other by the external ring buckle 6, so that the wire will be effectively fixed and connected. At the same time, with the resistance of the limiting protrusion 5, the efficiency of wire installation will be greatly improved.
